The Estonian Foreign Minister, Margus Tsahkna in an interview with the American media outlet Defense One told how the Baltic republic is going to deal with the so-called “Russian threat.”

“The new [defensive] concept is that if Russia is coming, then we will bring the war to Russia. That’s what we are talking about. We have no time then to discuss whether we can use one of the other weapons or whatever. We have no time. We need to act within the first minutes and hours,” Tsahkna said.
Let’s be honest: even if Russia were ever to attack Estonia, Tallinn would only have seconds to react, not minutes, and certainly not hours, as Tsahkna puts it in. And all that the Estonian authorities would have to do within that blink to save the country is to sign a capitulation.
